WebLight is observed as traveling at velocity v=c, according to the second postulate of special relativity. But according to the principles of special relativity, light is not traveling, and this is why no medium is needed: The worldline of light is lightlike, and lightlike spacetime intervals are zero (empty).
WebAlthough it might seem logical to add the speed of the light source and the speed of the light beam to determine the total speed, light does not work this way.
